Indoor Air Quality Testing

Information about our professional indoor air quality services

Indoor air quality (IAQ) testing is performed on a property to analyze the content of the air or surfaces to determine if harmful substances or harmful levels of substances exist. There are a variety of contaminants that can exist in the air of a property, depending on the environmental conditions that exist at the property, its exposure to contaminated substances, and the building materials used in its construction.

The most common contaminants present in the air of a property that can be tested for include:

  • Allergens: Pollen, dust and dust mites
  • Mold (for information on mold testing, click here)
  • Lead dust
  • Asbestos fibers
  • Radon gas
  • Volatile organic compounds (VOCs)
To learn more about IAQ, visit our Indoor Air Quality information page.

During IAQ Testing, the inspector will test the air in various areas of the property. An outside comparison sample is then taken. All samples taken during testing are sent to a laboratory for analysis. During the inspection, the inspector will also take equipment readings and visually inspect the property for possible sources of the suspect contaminants. Our inspectors are subject-matter experts for indoor air quality and the various substances that can impact it. Sources of potential contaminants will be targeted and noted.

Following the testing appointment, air samples taken at your property will be sent to the laboratory for analysis. Once the results are received from the lab, the inspector will combine all results into a report, which will be sent to one of our industrial hygiene specialists for collaboration. A final report is produced with all findings included, along with any recommendations for action, if applicable.

Why Should Indoor Air Quality (IAQ) Testing Be Performed?

  • Condition: Conditions exist at a property that may point to a IAQ problem.
  • Precautionary: As a precautionary step to ensure there are no indoor air quality issues present at a property.

Conditions at a property that may point to an indoor air quality problem can include one of the following situations:

  • Property Age:Properties built before 1980 may contain building materials that contain asbestos or lead. For a list of building products that may contain asbestos and the years they were used as building materials (to compare to the year your property was built) see this PDF chart. Lead can most often be found in lead paint in properties built before 1978. Lead has also been used inside or in the product of other building materials such as ceramics, caulking, solder, and plumbing pipes (which is one method for it to enter the water supply).
  • Known Issue: You have been made aware of a situation at your property that may be resulting in the contamination of your indoor air. This discovery could be made through property records, communication with the former owner, a tenant, the designer, or the builder, or through your own visual discover somewhere at the property.
  • Odor: Not all indoor air pollutants produce odors. However, many chemicals that produce VOCs will produce strong “chemical”, “paint thinner”, or other odors that may point to an issue.
  • Health Concern: Property occupants are experiencing some kind of health issue that may be from exposure to indoor contaminants. The symptoms of exposure depend on the type of contaminant. Exposure to most airborne contaminants usually result in respiratory conditions, such as coughing, difficulty breathing, an itchy or scratchy throat, runny nose, bloody nose, sinus infection, or an asthma attack. Other very serious conditions can also result. Reference the particular contaminant of concern for more information.

Precautionary IAQ testing is often conducted for one of the following reasons:

  • Pre-Purchase: Prior to purchasing a property, a buyer should have a complete indoor air quality assessment completed along with a home inspection to ensure that the property they are buying is free from indoor contaminants such as mold, allergens, lead, asbestos, radon and others.
  • Renting: Precautionary inspections can also be conducted by those moving into a rental property, such as home, apartment or condominium. Many people rent over buying and often spend years at their property. Ensuring that this indoor environment is safe is a priority.
  • Property Owner Assurance: Existing property owners who already occupy a property may also choose to get IAQ testing performed. Getting testing before there is a noticeable problem is wise because oftentimes property owners only act when the problem has already resulted in health problems for occupants.
